78079098 divided by 504 
We want to figure out the number of times 78079098 can be divided by 504.

Going ahead to step 1:
When dividing 7 by 504, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 504

On to step 2:
The number 504 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 504

Advancing to step 3:
504 goes into 780 1 times with a remainder of 276.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 276 after subtracting 504 from 780.
Append the next digit (7) from the dividend to 276 and continue with: 2767 / 504

On to step 4:
The number 504 fits into 2767 5 times, leaving a remainder of 247.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2520 away from 2767, we end up with 247.
Include the next digit (9) from the dividend after 247, then repeat: 2479 / 504

On to step 5:
2479 divided by 504 is 4 with a remainder of 463.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 2016 from 2479, we get 463.
Take the next digit (0) from the dividend and append it to 463, then repeat: 4630 / 504

Let's proceed to step 6:
If we divide 4630 by 504, we get 9 and a remainder of 94.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
If we take 4536 away from 4630, we end up with 94.
Bring next digit (9) of the dividend behind the 94 and repeat the process: 949 / 504

Going ahead to step 7:
949 divided by 504 is 1 with a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 15491.0
Subtract 504 from 949 to get 445.
Bring next digit (8) of the dividend behind the 445 and repeat the process: 4458 / 504

Step 8:
The number 504 fits into 4458 8 times, leaving a remainder of 426.
Record the quotient 8 as the next digit in the result. 
Result so far: 154918.0
If we subtract 4032 from 4458, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 9:
The number 504 fits into 4260 8 times, leaving a remainder of 228.
The next digit of our result is 8. 
Result so far: 154918.8
If we take 4032 away from 4260, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
2280 divided by 504 is 4 with a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 154918.84
If we take 2016 away from 2280, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
504 can be fit into 2640 5 times, resulting in a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 154918.845
Subtracting 2520 from 2640 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
504 can be fit into 1200 2 times, resulting in a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 154918.8452
If we subtract 1008 from 1200, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
The number 504 fits into 1920 3 times, leaving a remainder of 408.
Use 3 as the next digit of our solution. 
Result so far: 154918.84523
Deduct 1512 from 1920 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 14:
The number 504 fits into 4080 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 154918.845238
Deduct 4032 from 4080 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
504 goes into 480 0 times with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 154918.845238
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
504 goes into 4800 9 times with a remainder of 264.
Write down 9 as next digit of the result. 
Result so far: 154918.84523809
If we subtract 4536 from 4800, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final outcome is 154918.84523809, with a leftover of 2.64e-07.
